> The opnly other one I'm familiar with is HP's HPUX,
AIX is notionally a SysV derivative, but its userland "swings both ways" --
both SysV and BSD options and commands are generally acceptable.
I was a sysadmin for HP-UX and AIX systems back in the day. I liked PA-RISC;
it was a very clean "big RISC," even cleaner in some ways than PowerPC and
prototypical MIPS. I was sorry to see it become another casualty of the
Itanic. I still have a C8000 workstation in my office, the last of the PA-RISC
workstations (HP-UX 11i), and an HP 9000/350 (HP-UX 8). I also inherited an
Apollo 425t but I haven't fired it up yet, so I don't know if it's HP-UX or
DomainOS on it.

There is some BSD code in the kernel, but the userland is BSD, so that is
probably where much of the credit is owed.

Well, according to Wikipedia, the kernel is a hybrid. It is partly a March 3.0
microkernel and partly a (originally) 4.3BSD monolithic kernel.
